SOLUTIONS TO ENERGY CONSERVATION IN NORTHERN CLIMATES.

Energy conservation is now being approached through careful consideration of climatic conditions and siting. Mean annual ground temperature in relation to mean annual air temperature; heat loss through conventional basements; artificial and natural (earth) insulative properties; passive and active solar heating systems; and design in respons to immediate site conditions are discussed as design elements. These principles have been applied in the design of the Tymura Solar-heated residence located in north-western Ontario, Canada. Demonstrating a combination of passive and active space and water heating and partially underground construction, the completed residence is calculated to save up to 90% of its annual heating requirements.
